vThis invention relates V*to valves `andA'par-V i i to drive it up intoseatingpo'sition.

ticularly to that type employing a ball seat..

In valves employing a ball as a seating elem; ment it is desirable toleave the ball free in e'. order that y1t may rotate and present -acon-4 stantly changing seat. This prevents groov`V ingof the ball andmaintains the ball perectly round by allowing theball to present f a newseat at each operation.` The ac'com-" 3f panying difficulty with afreely suspended all, however, is that in its open position it isl freeto chatter and vibrate and thus create unduenoises in the valve.

It is the purpose of this invention to provide a valve employing afreely suspended ball as the seating element and in which the ball iscontrolled when unseated to prevent any chattering thereof.

'; Another common difficulty in avalve is the leakage which usuallyoccurs around the valve stem where it projects through the valve body orbonnet. Heretofore it'has been Vcustomary to pack thel valveystem toprevent Such packing, however,` generally requires frequent attention'`and lreplacement in order that there be no leakage around the stem whereit projects through the body.

the stem is eliminated. l

According to this invention the valve body is provided with a chamberfor the reception g; of the ball when it is unseated for retaining andcontrolling the ball out of the flow of fluid throughk the valve. y Itis preferred to retain and control lthe ball while in the ball chamberby creating a vacuum therein for re taining the ballin thev chamberwhile the fluid is passing through the valve; It is convenient to usethe iiow of fluid through the valve for this particular purpose. -Meansare alsozprovided for breaking the vacuum and permittingthe ball toassume its seating position and 'It is also `a purposev of` thisinventionftol provide a valve in which the leakage around to be heldtherein by the pressure of the fluid its retracted position in theballchamber and IIn order to eliminate the jusualV around the valvestemythevinner surface of the valve bodyfsurrounding the aperture throughwhich the stem Vprojectsisfformed inrsuch a` manner as to direct theflow of any' Water which Vshould'reach that portion, `away from thelstem `andin a.V direction to c`r ,ateV a suction around'fthe vstem*where it passes through the body'ratherY than an outwardly' exertedpressure.- better understanding' will be had of this invention-trom thefollow ing description taken in connection with the" drawingin which: .jF ig. I is a vertical longitudinal section throughV the center of avvalve constructed in accordance withthis, invention.

igrQ is la section on line/'2 2 of l, an v Fig. 3 isa section on line3-3 of Fig. l,

The valve comprises a body formed"` of two sections, l and'2`threadedtogether along a horizontal plane. The two sections kare circu-4 lar incross section land areo greater diam# i renate eter at theline'ofjointurethan at the ends y thus presenting a somewhat bulbousconfigu-` ration. The lower section 2 terminates 1n an inlet nipple 3and the upper sectionllrA is.;`

formed with an integral bonnet 4l for hous# ing the valve stem and valveactuating mechanism later to be described. The bonnet is provided withthe usual outlet spout 6. Ad-

jacent the upperv end of Vthe body portion 1 and approximately wherethebonnet iijoinsl thereto, the body is formed with an annular valveseat 7 adapted tobe closed by a valve ball 8. Immediately belowtheball 8the body y is formed with a ball chamberr9 of cylindricalformation'deined by an' annular wall Il, the chamber being open atits'upper end and in position to receive the ball 8. The lower-end ofwall l1 is. formed with a reduced opening 12. of lesser diameter thanthe diameter of the ball. Below theaperture 12 the' body' is formed witha baiile or :deliectonl disposedV symmetrically with respect to theinletandd having wing portions ",.ll approaching Vthe sides ofthe housing Vto4form passages if Y Y terminating in jets 17'."` The jetsl? enter into5, 'ti/on: iscreatedin the lower portions of chan-rV two circularchannels or ducts .18, one passing up along each side of the wall 11 ofthe ball chamber and leading to an annular chamber 19 immediately abovethe open end ofthe ball chamber 9. The relation of the jets 17 withrespect Vto channels 18 is such as to create an *Y Y Y lejection actionin the lower portions of channels 18 which' will tend to create asuction or partial Vvacuum in the chamber 9. Y Immediately above thevalve seat 7 the bonnet Ir is providedV with a Yrestricted vpassage orport 21 adaptedto `be partially or totally closed by the tapered portion22 of the valve' Astem 23. The valve-stem 23 is provided with anintegral worm 24 engaging aworm nut` 26 cast integrally-'with thebonnet.It will be Y seen that when the valve stem 23 Vis in its up!wardposition the taperedportion 22 thereofVr will,v close or atleastpartiallyclose therestricted opening 21. Immediately above thel vtapered portion 22 the stem is provided withv asecond l. tapered portion27 `of' a maximum diameter slightly less than the .diameter of theopening 21, It will be seen from the above thatr whenftlie valve Vstem23 is turned vertical'-v ly, downward `'that vthe portion 22 will moveaway from the restricted'opening 21, 'whereas v the porti0n-27'of thestem will move to-y ward the restricted opening 21 to restrict the flowtherethroughbut being Smaller than the opening will never entirely stop`the flow.

, In order to prevent leakage around the vstem where it passes throughthe bonnet and to eliminate the necessityv vof packing andV pack-A ingnuts, the'upper end of the bonnet is curved inwardly and downwardly asat 28 thus providing an annular concave inner surface surrounding' thest em 23. The stem 23 is pro-v In' thenormal closed Condition of thevalve the stem 23`is up and the portion 22 thereof .totally orpartiallyl closes the opening `21 i; e.

the portion 22 need not seal the opening tightly. `Underthis conditionthe valve .ball 8 will be seated against seat 7 and lloe held tightlythereagainst bythe `pressure of the fluid,"'s'uchy as water, Ypressingagainst` the 'l lower surface thereof.

After all water has been withdrawn,

a partial vacuum will be created in chamberv 9 and retain ball 8 inthelower portion of j Y chamber 9 where it will seal the opening 12, Thewater passing through channels 18 will enter into the passageA 19, pass.through the openingm'21upiinto kthe bonnet vand out Y through the spout6. Once the lball has been dislodged by the stem, the flow through therestricted opening V21 may be controlled vby adjusting'zthe stem'23 vandthe portion 27 not rattle or' vibrate. Y

When the. portion'22substantiallycloses the opening 21 there will be,

created a water-'hammer which will cause the water to surge suddenly fVdownwardly through channels 18' and 'back upwardly through the opening12, the flow thereof being aided by the upperV curved portion'of. thebathe 13. `The waterflowing in this re-i versed direction will impartasudden impactV tothe ball 8 and drive it upwardly against its'seat 7vwhere itv will beheld the pres- V sure of the incoming water.
